Power Values missing from downloaded data

Hello. I am new to PVOutput, so I might be missing something.

My live graph and the table below the graph are showing the Power used and Power Generated values correctly. When I download the values from the download option, the Power_out and Power_in values are empty.

Is it supposed to be like that, or am I doing something wrong?

The download link gives the raw data that was uploaded, in this case no power was uploaded.

Power values shown on the system page are calculated.

Thanks @bankstownbloke , that makes sense.
